Thank you for visiting greinerjazz.com!  Please enjoy looking around and seeing what musical groups I have to offer and where I will be performing, both with my groups and others as well!

I'm very passionate about offering the best live jazz possible.  My goal is to both entertain people and to give them the best live music they have ever heard.

We are willing to travel anywhere and do any type of gig!  Don't hesitate to get in touch with me via the e-mail link below if you have any questions regarding the jazz trio/quartet, Little Big Band, SwingShift Big Band and JG's Four Brothers.

Thanks again!  Enjoy your visit and come back often to find out where you can see me perform live!
